I processed some Delta 3200 in DDX yesterday and it looks pretty grainy to me under the loupe. However it enabled me to use a Holga as it was getting dark. I use 1+4.

I found DDX to produce very little grain in the 1+4 and 1+9 dilutions.
Even Delta 3200 looks good

Thanks, this is the answer I was looking for. I am thinking of
switching from DDX to ID-11 in order to get slightly less grain. But,
DDX is very convenient, as it is already diluted and it is easy to make
slightly different dilutions, like 1+4, 1+6, and 1+8, for different
purposes.
